TIME-COURSE OF TROPONIN-I, MYOGLOBIN, AND CARDIAC ENZYME-RELEASE AFTER ELECTRICAL CARDIOVERSION

The results of this study, conducted in 25 patients without myocardial infarction, showed that all the biologic markers of myocardial infarc tion, except the highly cardiospecific cardiac troponin I, increased i n some patients after electrical cardioversion. These results allow us to conclude that electrical cardioversion, even preceded by a mechani cal resuscitation of short duration, does not result in myocardial dam age, and that cardiac troponin I is more, accurate than creatine kinas e-MB activity and creatine kinase-MB mass determination for the diagno sis of myocardial damage in patients who have undergone electrical car dioversion.
